In this work, waste marigold flowers from Temple were used as adsorbent to remove cadmium (II) and chromium (VI) ions from aqueous solutions. Influences of initial heavy metal concentrations, contact time, adsorbent dose, temperature and initial pH on removal of cadmium (II) and chromium (VI) ions were studied under batch mode of operation. Both the adsorption process of cadmium (II) and chromi...

Maternal undernutrition is linked with an elevated risk of diabetes mellitus in offspring regardless of the postnatal dietary status. This is also found in maternal micro-nutrition deficiency, especial chromium which is a key glucose regulator. We investigated whether maternal chromium restriction contributes to the development of diabetes in offspring by affecting DNA methylation status in liv...

The oxidation kinetics of chromium at 900~ are independent of the oxygen partial pressure. Although this observation gives evidence for a defect mechanism where chromium interstitials account for the chromium transport in the oxide scale, the experimental phenomena do not support one single model. The occurrence of oxide whiskers and oxide ridges are explained by the energy of activation for th...

The activated sludge has been acclimatized with chromium (VI) ions from 5 mg/L to 20 mg/L. It is observed that the chromium removal percentage, COD removal and mixed liquor suspended solid (MLSS) decrease with the increase in dilution rate. Maximum food to microorganisms ratio (F/M) is found to be 0.19. When initial metal ion concentration increases from 5 mg/L to 20 mg/L, the chromium removal ...

In some studies in diabetic people, chromium picolinate supplementation has lowered readings for both plasma triglycerides and blood sugar. In the present study, relatively low dose supplementation (200 μg chromium) did not lower blood sugar readings, but did lower triglyceride values in people with the following characteristics: type 2 diabetes, moderately elevated blood sugar, and not using i...

the biosorption of hexavelent chromium from saline solutions by posidonia oceanica, a marinebiomass, was studied as a function of ph, initial chromium (vi) and salt (nacl) concentrations in batchsystem. the sorbent exhibited the maximal chromium (vi) uptake at ph 2 regardless of the presence ofincreasing salt concentration. equilibrium uptake increased with chromium (vi) concentration up to 250...

Batch adsorption experiments were performed for the removal of chromium (III) and chromium (VI) ions from aqueous solutions using Canadian peat and coconut fiber. The Langmuir model was used to describe the adsorption isotherm. The maximum adsorption for peat reached 18.75 mg/g for Cr(III) and 8.02 mg/g for Cr(VI), whereas the value for fiber was slightly higher and reached 19.21 mg/g for Cr(II...

BACKGROUND Five metal turners employed by an aerospace manufacturer presented to the Birmingham Chest Clinic occupational lung disease unit. Four cases of occupational asthma (OA) due to chromium salt (3) and cobalt (1) were diagnosed by serial peak-expiratory flow measurements and specific inhalation challenge testing. AIMS To measure the extent of the outbreak and to provide epidemiological...

BACKGROUND Several authors, mostly on the basis of nonrandomized studies, have suggested dietary trivalent chromium supplementation as an attractive option for the management of type 2 diabetes and for glycemic control in persons at high risk of type 2 diabetes. OBJECTIVE The study aimed to determine the effect of chromium on glucose and insulin responses in healthy subjects and in individual...
